Danfoss ECtemp 530 Electronic Thermostat

Introduction

ECtemp 530 is an electronic thermostat provided with a 2- pole switch and a wire sensor to measure and control the desired floor temperature. It can be either flush-mounted (standard) or surface-mounted (using special box).
The thermostat has a button for adjusting the temperature
setting with a scale from () 1 to 6 (each step corresponds to approximately 8 °C). Furthermore, it has a LED indicator showing standby periods (green light) and heating periods (red light).

Safety Instructions

Make sure the mains supply to the thermostat is turned off before installation.

IMPORTANT: When the thermostat is used to control a floor heating element in connection with a wooden floor or similar material, always use a floor sensor and never set the maximum floor temperature to more than 35 °C.

Please also note the following:

• The installation of the thermostat must be done by an authorized and qualified installer according to local regulations.
• The thermostat must be connected to a power supply via an all-pole disconnection switch.
• The sensor is to be considered as live voltage. Have this in mind if the sensor must be extended.
• Always connect the thermostat to continuous power supply.
• Do not expose the thermostat to moisture, water, dust, and excessive heat.

Mounting Instructions

• Place the thermostat at a suitable height on the wall (typically 80-170cm.).
• In wet rooms, place the thermostat according to local regulation on IP classes.

Note: A floor sensor enables a more accurate temperature control and is recommended in all floor heating applications and mandatory under wooden floors to reduce the risk of overheating the floor.

• Place the floor sensor in a conduit in an appropriate place where it is not exposed to sunlight or draft from door openings.
• Equally distant and >2cm from two heating cables.
• The conduit should be flush with the floor surface – countersink the conduit if necessary.
• Route the conduit to the connection box.
• The bending radius of the conduit must be min 50mm.

Follow the steps below to mount the thermostat:

1. Open the thermostat:
   • Press the release tab in the bottom of the thermostat using a flat object.
   • Carefully detach the front cover.
   • Carefully detach the frame.
2. Connect the thermostat according to the connection diagram.
   By connecting an external timer to the terminal marked by a moon symbol (and by using for example the same phase as for the mains power supply), the thermostat can be set to reduce the temperature by 5 °C during specified periods.
   The screen of the heating cable must be connected to the earth conductor of the power supply cable by using a separate connector.
   Note: Always install the floor sensor in a conduit in the floor.
3. Mount and reassemble the thermostat.
   • Fasten the thermostat to a socket or an exterior wall box by driving the screws through the holes in each side of the thermostat.
   • Install the frame and front cover in the reverse order of disassembly.
4. Turn on the power supply.

Settings

How to change the minimum and maximum floor temperatures

1. Remove the adjustment button.
2. Move the pins to the desired positions.
3. Put the adjustment button back in place.

Note: Please be aware of the following:

• The floor temperature is measured where the floor sensor is placed.
• The temperature of the bottom of a wooden floor can be up to 10 degrees higher than the top.
• Floor manufactures often specify the max tempera-ture on the top surface of the floor (usually 27-28 °C).
• Always use a floor sensor to control floor heating. Without a floor sensor, the temperature control may be less accurate and you risk overheating the floor.
